Czech speaker here. They're people from Eastern Slovakia, don't appear to be very educated. The letter is older, from the Communist era. They say thank you for getting back to us, we wanted to contact you, but didn't have the adress. Then they ask for sending curtains and headscarves, say that he and his wife don't work, because they're unabe to work. His wife is ill with heart. They started to repairing their house, but they don't have any material. They ask for money. They say they're giving their photographs to some guy named Stanko and he'll deliver them to your family together with dried mushrooms. Then they talk about family history, how old are they and their kids, etc. And they ask your family to write "czechoslovakian", because they can't read "their language". Really boring stuff.
